(9 pts) Write reactions for three different syntheses of 2-pentanol using reagents of four carbons or...
4) (2 pts each) Outline a synthesis (i.e., simply show the reagents/reactants for the necessary reactions) for each compound below from the designated starting material. Use reagents you've learned about in Orgo I and II. The number of arrows does not necessarily correspond to the number of steps required. As a general rule, any carbon units in the products that were not in the starting materials should come from molecules containing 7 or fewer carbons. Things that don't end up...
8. Show how you would accomplish the following syntheses. You may use whatever additional reagents you need. The synthesis should not take more than three or four reactions. At least one of the reactions should come from the aldehydes and ketones chapter. (6 pts) a) CO2H b)
III. Grignard Reagents. 1. (6 pts) Provide two different syntheses for 1,1-diphenyl-1-butanol starting from a carbonyl compound and using a Grignard reagent. Synthetic Route 1: carbonyl Grignard reagent a) THE b) H3O+ work up OH 1,1-diphenyl-1-butanol Synthetic Route 2: carbonyl Grignard reagent a) THE b) H3O+ work up 1,1-diphenyl-1-butanol
Please explain the mechanisms!
1. Propose a synthesis for each of the following problems starting with reagent shown and using any other organic or inorganic reagents allowed in each problem. Multiple steps are required. The number of steps you use does not matter. Reactions should give the desired product as a major product. For full credit show the product of each step (reaction). If you make use of organometallic reagents such as Grignard, Wittig, organolithium, organosodium, organocopper, etc. you must...
1. (6 pts) Provide two different syntheses for 1,1-diphenyl-1-butanol starting from a carbonyl compound and using a Grignard reagent. Synthetic Route 1: carbonyl Grignard reagent a) THE b) H30* work up 1,1-diphenyl-1-butanol Synthetic Route 2: carbonyl Grignard reagent a) THF b) H30* work up ОН 1.1-diphenyl-1-butanol 2. (3 pts) The use of Grignard reagents requires scrupulously dry aprotic solvents such as diethyl ether or tetrahydrofuran. Please explain why the solvents need to be scrupulously dry. To support your reason, show...
Write the three isomers of C4H10O. Try to make at least 3 isomers using 4 carbons, 10 hydrogens and one oxygen atoms. Make sure that the number of covalent bonds for C (four), O(two), and H(one) are correct, and you used correct numbers of each atom. You can also branch the carbons as shown in your text book and previous slide. Make structures of at least 3 isomers having the same molecular formula but different connectivity. (You can make as...
8 This synthesis requires more than 1 step-propose a route giving all reagents (include solvents) required and drawing the structure of all stable, neutral intermediate compounds. [6 pts 9. Nether of the reactions drawn below will give the product shown. Draw the product that will form instead giving a mechanism as an explanation. [10 pts) HBr ether Br 11. Are these statements True or False? (2 pts each = 4 pts] a) Fluoride ion is a more reactive nucleophile in...
Devise a synthesis of (Z)-3-octene using one of the starting materials and any of the reagents below using the fewest steps possible.

2. Write in the reagents required for the following reactions. More than one step may be required to form the product. OH OH
Multistep Synthesis (9 pts) Show how to convert benzene into at least one of the molecules below using any reagent. You should be able to do this in three steps but this is not a required minimum or maximum. If you are not sure of an intermediate step put down structures and as much as you know about reagents to maximize partial credit. You may attempt more than one and the best will be graded. It is ok if a...
